Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sash grechant (glazing channel) for fixing a glass to a sash ridge, and more particularly to a sash grechant for fixing a single plate glass to a sash for a multi-layer glass and a method for attaching the sash grechant.
[0002]
[Prior art]
Conventionally, glazing channels (hereinafter referred to as “Grechan”) made of resin or the like are provided on the outer periphery of a glass housed in a sash cage over four laps. By providing the Grechan, it is possible to protect the peripheral edge of the glass and ensure the sealing performance.
[0003]
In order to improve the heat insulation and the design of the indoor side, a composite sash is widely used in which the exposed portion of the metal frame or metal tub on the indoor side is covered with a resin frame or resin tub. In this case, the glass fixed to the ridge generally uses a double-glazed glass in order to ensure heat insulation.
[0004]
For example, Japanese Patent Application Laid-Open No. 10-317805 holds a glean for fixing the double-glazed glass to the ridge, and is sandwiched between sashes and fixed in pressure contact with the indoor side surface and the outdoor side surface of the double-layer glass. In the case of a composite sash, since a resin cage formed in a hollow shape is attached to the exposed portion of the metal cage on the indoor side in order to improve heat insulation and ensure strength, the expected width of the sash is larger than that of a normal sash. In addition, since the multi-layer glass is attached, it is thicker than the case of the single plate glass, and therefore the Grechan is formed wider.
[0005]
On the other hand, in a sash that does not require much heat insulation, a normal sash in which the sash is entirely made of metal is used. In this case, since glass does not require so much heat insulation properties, single plate glass is generally used. Here, the Grechan which fixes the single glass is formed narrower than the case where the multi-layer glass is fixed.
[0006]
[Problems to be solved by the invention]
However, even for a sash that does not require much heat insulation, a composite sash may be used to improve the design of the indoor side. In this case, it is more cost-effective to use single plate glass than to use double layer glass. However, the conventional Grechan used for fixing a single glass sheet has only a narrow width, and there is no one suitable for a composite sash.
[0007]
The present invention has been made to solve the above-described problems, and is a grechant capable of attaching a single plate glass to a sash bottle for a multi-layer glass, and firmly fixing the glass in a glass opening groove of the sash bottle. An object of the present invention is to provide a sash grechant that can be used.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the sash grepant according to the present invention is substantially the same width as a glass insertion groove into which a multi-layer glass of a composite sash fence in which an indoor exposed portion of a metal bowl is substantially covered with a resin bowl can be inserted. In the sash Grechan consisting of the Grechan body formed in
